摘要:
The invention provides compounds of the general formula I:
(in which R1, R2 and R3, which may be the same or different, represent a hydrogen atom, an alkyl group containing 1-6 carbon atoms, a nitro, amino, alkyl-substituted amino, hydroxy, carboxylic, alkoxy, aryloxy or heterocyclic group, or a halogen atom, and in which the alkoxy group may be substituted by a hydroxy or alkoxy carbonyl group; and pharmaceutically acceptable non-toxic salts threof including esters of those compounds in which the groups R1, R2 or R3 represents a carboxylic group. Pharmaceutical compositions containing these compounds are also provided as well as methods for production thereof.
